Question

find the points which divide line segment joining 1/-3 b-3/9 in the ratio 1:3 externally internally
​

Answer 1

Step-by-step explanation:

let the point be P(x,y)

x=(m2x1+m1x2)÷(m1+m2).

=>(3×1+1×-3)÷(1+3)

=>(3-3)÷4

=>0/4

=>0

y=(y2m1+y1m2)÷(m1+m2)

=>(9×1+3×-3)÷(1+3)

=>(9-9)÷4

=>0\4

=>0

so, P(0,0)

It's origin.

I hope this answer helps you.
